DISPLAY HOLDER Application filed October '7, 1929. Serial No. 397,897.

This invention relates to an improved display holder for use in conjunction with artificial teeth, and has for its primary object to provide a structure in the form of a holder which is of such nature that artificial teeth may be quickly and positively connected therewith for purposes of display and yet may be readily disconnected from said holder whenever desired, the construction being such as to permit' of the handling of the mounting upon which the artificial teeth are carried and to enable such mounting to be subjected to the jolts and stresses incident to handling operations, without permitting the teeth to become accidentally disconnected from their positions of application upon the holder or mounting.

A further object of the present invention is to provide a backing or base of wood, rub her, or other nonmetallic material to which is applied a series of novel metal, inverted, L-shaped clips for the detachable reception of artificial teeth.

A further object of the present invention is to provide a novel form of clip of the character stated having a relatively broad plate provided with serrated edges so as to more readily retain the clip upon the backing or base when the clip is driven to place.

A further object resides in the provision of a relatively resilient, single prong for said plate, which prong is curved or bowed.

The invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawing forming part hereof, and in which:

Fig. 1 is a face view of a display holder embodying the invention.

Fig. 2 is a view in section taken upon the line 22 of Fig. 1.

Fig. 3 is a view in section taken upon the line 38 of Fig. 1.

Fig. 4 is a view in cross section of the device embodying the invention.

Fig. 5 is a view in perspective of one of the clips shown in the foregoing figures.

For the pilrpose'of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is'to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organiZa-tion of the instrumentalities as herein shown and described.

Referring to the drawing, the reference numeral 10 designates a base or backing, rectangular in shape, and formed from wood, rubber, or other non-metallic material. The base or backing has driven thereinto a plural ity of aligned clips of inverted L-shape, which clips are equally spaced apart and are arranged to receive artificial teeth 11. Each of these L-shaped clips, which are formed from spring metal, is provided with a rela tively broad, flat plate 12 the edges of which are serrated at 13 and one end of which is somewhat pointed, as at 14. The opposite end of the plate 12 terminates in a relatively resilient member 15. The member 15 is relatively narrow and is somewhat curved or bowed to provide-the forwardly extended portions 16 and 17, and there is also formed upon opposite sides of the juncture of said member 15 with said plate, shoulders 18. The artificial teeth are slotted at 19. The slots of the teeth have one of their ends terminating near the cutting edge of the teeth, while the other ends of said slots open at the opposite ends of said teeth, and in view of this fact the teeth can be easily attached to the backing by simply placing the teeth, with their flat sides upon the backing and upon sliding the teeth transversely the clips will ride into the slots and compress the clips so that the latter will exercise a constant pressure upon the teeth to hold them against accidental disengagement from the backing. This is possible because of the parti ular shape of member 15 since the parts 16 and 17 abut against the wall of the slot in a tooth pressed by the bowed member. In practice the shoulders limit transverse movement of a tooth 11. In

r, orrcs cry.

practice the relatively pointed portion 14 of late 12 serves to aid in driving the latter into a base or backing and the serrated edges of the plate provide a good anchorage, which is important since the artificial teeth are frequently removed and replaced, thus plac ing stress and strain upon the clips.

WVhat I claim is:

An artificial tooth engaging device of the characterstated comprising an integral metal structure stamped from a single blank and consisting of a thin, flat, relatively broad plate arranged to horizontally penetrate the base of a carding device, said plate having a centrally arranged pointed inner end and serrated side edges, said plate having extended therefrom at substantially right angles thereto a pendant outwardly curved spring arm to removably accept an artificial tooth, said spring arm being arranged in alignment with the pointed end of said plate.
